Why we use AWS Provider?

We use the Amazon Web Services (AWS) provider to interact with the many resources supported by AWS. You must configure the provider with the proper credentials before you can use it.

Steps to follow for VS Code with terraform

Create a file with terraform.tf

terraform {
  required_providers {
    aws = {
        source = "hashicorp/aws"
        version = "~> 5.0"
    }
  }
}

# Configure the AWS Provider
provider "aws" {
  region = "eu-west-01"
}

Create an ec2 file :

We are creating an ec2 isntance

For quick reference of key-pair write go to https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/key_pair

https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/default_vpc

https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/security_group

Code for ec2

 resource "aws_key_pair" "terra-key-vscode" {
   key_name = "junoon-key-vscode"
   public_key = file("junoon-key-vscode.pub")
 }

 resource "aws_default_vpc" "default" {

 }

 resource "aws_security_group" "my_sg" {
   name = "my zplus security"
   description = "only this description"
   vpc_id = aws_default_vpc.default.id

   ingress {
     description = "allow access to SSH port 22"
     from_port = 22
     to_port = 22
     protocol = "tcp"
     cidr_blocks = ["0.0.0.0/0"]

   }
   ingress {
     description = "allow access to http port 80"
     from_port = 80
     to_port = 80
     protocol = "tcp"
     cidr_blocks = ["0.0.0.0/0"]
   }
   egress {
     description = "allow all outgoing traffic"
     to_port = 0
     from_port = 0
     protocol = "-1"
     cidr_blocks = ["0.0.0.0/0"]
   }
   tags = {
     Name = "my z plus sec"
   }
 }

 resource "aws_instance" "my_instance" {
   ami = "ami-0e9085e60087ce171"
   instance_type = "t2.micro "
   security_groups = [aws_security_group.my_sg.name] #interpolation
   key_name = aws_key_pair.terra-key-vscode.key_name #interpolation

     root_block_device {
       volume_size = 10
       volume_type = "gp3"
     }
 }

Terraform in local - vscode : Check AWS is configured?

Go to terminal and write
```
 aws configure
```
First check aws is installed or not in your windows machine

https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html

Download AWS cli for local (windows)
Configure AWS in local: Fetch credential with AWS EC2

Go to your EC2 AWS where you have configured AWS cred before, copy

access key and secret access key.

Go to your VS-code local terraform and configure the credential there:

This how you can configure AWS CLI in VS-Code AWS
To check AWS CLI in VS-code is configured or not
```
 aws s3 ls
```
Yes, done I’m getting the output.
Now initiate the terraform file with apply
```
 terraform init
 terraform plan # to check everything is correct
 terraform apply
```
These all files will be create with the following commands

You will get instance running in “Ireland region”

successfully running
To access ec2 created with terraform : with ssh

Revoke the permission with
```
 icacls junoon-key-vscode /inheritance:r /grant:r "DELL:R"
```
Copy your ssh client form aws ec2
```
 ssh -i "junoon-key-vscode.pem" ubuntu@ec2-34-255-7-235.eu-west-1.compute.amazonaws.com
```
do not forget to remove .pem then run

Successfully connected AWS EC2 with VS-code
